: One object of the invention is to provide an improved machine of the type specified in which the winding-spindle or cop-holder- .moves away from thedrive-roll in a certain 10 predetermined path'a'nd is tilted in angular relation thereto, during. the winding of a conical cop or package, whereby to build the cone with. a gradually increasing taper on its periphery and with concavo-convex ends.

simplify the construction of the machine, to render its mechanism more compact, and

generally to increase its efliciency while mak ing it more convenient of operation. I 2 A preferred embodiment of the inventipn is described in the following specification and illustrated in the accompanying draw ings by way of example only. In the draw- 1ngs:'

Fig. 1 is aside elevation of a portion of the'improved winding machine showi the winding-spindle or cone-holder, the riveroll therefor, and the general arrangement of the "cone-builder motion;

Fig. 2 is a plan view of the Fig. 3 is a front view of a portion of the machine showing the cohe-holder,'its driveroll and the traversing-means for the thread guide which lays the yarn or thread on the cone, the parts being illustrated in position at the commencement of the winding;

0 cone-holder Figfl is a similar view showing the coneholder in position removedfrom the driveroll at or near thecompletion of winding the cone and I Fig. is a detailed view of the doggingmechanism which'actsfito hold theconeholder in raised position.

The improved machine is usuall constructed in gang form with a plura ity of winding units arrangedih series along a suitable frame or bed.- In the present drawings the frame of the machine isillustrated 0' .me 1 e1y-in fragmentary view, and only the g gntial operating-elements of a single windlng-umtxare shown. Referring particularly to Fig. 1, the refer- Further' objects of the invention are to drive-shafts extend horizontally at rightangles with respect thereto. The framemembers 2 carry-bearings 3 fora cam-shaft 4 on which is mounted a c lindrical "cam 5.

As shown more particular y in Fig. 3, the cam-5 has one or more helical cam grooves 6 and 7 for engaging a stud or roller 8 which travels therein. The rollr 8 is connected to a thread-guide 10 which slides on a'horizontal track or rod 11, and-as the cam is rotated {from its shatt 4 the guide isreciprocated therefrom to traverse the yarn on the cop or cone. jUsualliy, a separate cam is provided for each win g unit, but in other cases one cam may} be employed to reciprocate a series of thread-guides carried on a slidable rod or bar.

Journaled in bearings 12 above the camshaft 4 is a second shaft 13 which carries the driverolls 15 arranged in series therealong, one for "each winding unit. The thread-guide-lQ'reaches up above the driveroll 15 and is provided with a slot or groove .16 through whichthe yarn 3/ leads to direct it on to the coporlcone-holder 20. The copor cone-holder 2O is 'constituted "in a suitably shaped mandrel which is rotatable .on-a dead-spindle 21 and adapted to carry a paper cop-tube or other yarn-receiver. Thejspindle 21 is hinged between the sides of a forked bearing-member 22 and has a notch 23 in its butt-en r which is engaged by a projection 24 on a flat spring 25, see Fig.

2 The spring 25 is secured .at 26 to the side of the forked bearing-member 22. The spring 25 thus holds the spindle 21.normal1y extending at right angles to 'the bearingmember 22 to support, the cone-holder 20 With its axis in the vertical plane of the axis of the drive-roll 15. .The bearing-membr 22 is provided 'with upwardly extending arms 27. formed with hubs 28 which are bored to receive a .stud 29 projectingffon wardly from. an elbowshfipedarm 30'. The 'hubs 28 thusserve to rockabl support thebearing-member 22 from the; rm 30 anda split collar 31 is clamped around the stud 29 between the hubs to hold the member in place thereon.

The arm 30 constitutes the main support and lifter-means for thecone-holder 20, be ing hinged or pivoted to swing upwardly during the building of the cop or cone. The arm 30 is formed with spaced bearing-hubs 32, 33, see Fig. 2, which straddle the sides of a forked bracket 34 supported from the cross-girt or frame-member 2. A horizontal rod or shaft 35 is held fixedly in the top of the forked bracket 34 and projects through suitable boresin the hubs 32, 33 of the arm 30 to pivotally support the latter therefrom. A collar 36secured to the end of the rod 35 abuts the bearing-hub 33 of the arm 30 to hold the arm in place on its pivot.

Between-the hub 32 of the arm 30 and the opposite side of thebracket 34 is a loosely mounted hub 37 carrying an arm 38 which pivots on the rod 35. The arm 38 carries cal support or standard 43 forming a part of the bracket 34,- see Figs. 1 and2. Throug aniarcuate, grooved guiding-track 40 .at its outer end which serves as the prime means for. controlling the tilting action of the coneholder 20 as it rises with its support or arm 30. The arm 38 has an arcuate slot 41 in its side, through which extends a bolt 42 adapted to tighten the arm against a vertithis means the arm 38 is adjustable on the rod 35 as a pivot to raise or lower the guid ing-track 40 at its forward end. .Referring particularly to Fig. 4, the groove 45 in the front of the track 40 is inclined at an angle to the vertical and an arm 46 reaches downwardly from the bearing-member 22 with a stud or roller 47 at its end engaging. the groove. The inclined groove or guideway 45 is in effect a cam ada-pted'to act on the follower roller 47 of the arm 46 to rock the bearing-member 22 on its pivot to tilt the cone-holder 20 as the latter moves upwardly, this action being hereinafter more fully explained.

The come -lifter arm 30 swings upwardly with the cone-holder 20 during the increase in diameter of theuwinding and suitable.

means are provided to prevent a. retrogressive movement thereof. Any preferred construction of dogging-mechanism may be em ployed for this purpose and Fig. 5 illustrates a preferred form of construction thereof. Referring to this view and Fig. 1, an arcuate member or sector 50 is fixedly attached to the side of the arm 30 and extends downwardly in substantially concentric relation with the pivotal axis of said arm. The sector 50 may be attached to the arm 30 in any suitable manner and, as shown in Fig. 2, isinserted in a slot 51 in the side of the arm and clamped in place by a bolt 52 and washer 53. The sector 50 is provided with ratchet-teeth 55 on its rearward side pawl by means of a spring 63. As the arm 30 rises the sector 50 moves upwardly therewith and the ratchet-teeth 55 on its side are successively engaged by the end of the pawl 56 to prevent retrogressive movement of the arm. The sector 50 is also engaged by a friction-dog which is spring pressed against its forward curved face; this dog 65'a1s0 cooperating with suitable stoppingmechanism to arrest "the operation of the machine when the winding of the cop or cone is completed. These latter elements form the subject-matter of a separate application and are therefore not herein shown or described in detail. A screw 67 screwed through alug 68 on the arm 30 is adapted Having now described the constructlon and arrangement of the various parts of the improved winding machine its method of operation will next be explained. To pre pare the machine for winding the dog 56 is released from the ratcheton the sector 50 and the arm 30 lowered into position with the cone-holder 20, or the cop-tube carried thereby, resting against -the periphery of the drive-roll 15, see Figs. 1 and 3. As'the coneholder 20 is brought down into contact with the drive-.roll'15 the follower roller 47 slides down to the bottom. of the inclined groove or guideway 45 in the cam-track 40. The pur ose of the adjusting-means for the camtrac 40 is to provide that the track may be set in proper relation to the cone-holder 20 to insure that the latter will bear evenly along the whole length of the drive-roll 15 as shown in Fig. 3; it being understood that when cone-holders ,of different dimension or taper are employed on the machine the relafrom its clamping means so that when the cone-holder 20 is properly placed to rest on the periphery. of the drive-roll 15 the camtrack 40 may be adjusted in position with the roll engaging its groove 45 without any tendency for the cam to tilt or tip the cone- ,holder to remove it from a full contact with the surface of the drive-roll.

With the parts set in the proper relation source of power to rotate the cam 7 to traverse the thread-guide 10, and to drive the roll 15. to rotate the cone-holder 20. The

yarn a leadsthrough the slot 16 in the thread-guide 10 and as the latter is reciprocated through the engagement of its'roll 8 with the groove 7 in the'cam 5 the yarn y will be traversed back and forth on the cone-holder 20 to deposit it in helical coils crossing each other at intervals between the endsof the cone-holder. In U. S. patent to Taylor, No. 1,588,918, granted June 15, 1926, it is explained that thetwo grooves in the traverse-cam are of difierent pitch or lead to provide for regulating'the traverse of the thread-guide in accordance with the type of package being wound; one groove being operative on the guide when the ma Y chine is employed for Winding cones and the other groove being used when the machine is ad usted for winding cylindrical packages. The present invention is concerned only with the Winding of conical packages ment,..as noted in the patentpreviously re and the groove 7 in the cam 5 is plotted with a progressively changing pitch or lead for the purpose of accelerating the speed of the thread-guide as it traverses toward the smaller end ofthe cone and correspondingly retarding its speed as it moves toward the base of the cone. The object of this arrangeferred to, is to cause the yarn to be laid on the cone-holder with the coils or helices having an increased pitch or lead toward the apex end of the cone'as compared with their disposition at the base end thereof. This results in the yarn building up faster at .the base of the cone than toward its apex end so that the taper on the surface of the package. gradually increases from start to finish of the winding. This increase in the taper takes place as the cone-holder 20 reg cedes-from the drive-roll 15, and to provide that the surface of the winding, notwithstanding its change in taper or conicity, be

' maintained constantly in full contact with cal the periphery of the drive-roll it is necessary that the cone-holder be tilted to progressively increase the angle of inclination of its axis with respect 'to the drive-roll as the holder recedes from the roll. As the cone-holder is forced upwardly from the drive-roll 15 by the increasing mass of the cone being wound the arm swings upwardly about its pivot 35, and meanwhile the bearing member 22 is rocked on its pivot 29 under the action of the. cam-track '40. That is to sayfas the cone-holder 2O rises away from the drive-roll 15 the roller 47 on the arm 46 slides through the cam-groove. 45, and since the groove is inclined at an angle to the normal vertic path of the arm longitudinal direction of its base.

from. Moreover, since the axis of the coneholder 20 is oifset or displaced below the pivotal axis on which the bearing-member swings the tilting of the cone-holder 20 will also cause it to be shifted bodily in the I Stated briefly, the tilting of the cone-holder on an axis out of line with its own axis causes the holder to be displaced bodily to the right longitudinally of the drive-roll 15 during the movement of the holder away from the roll. Now since the path of traverse of the thread-guide 10 is constant with respect to the drive-roll 15 the layers of'yarn deposited on the cone-holder will be gradually and progressively stepped forward in, the direction of the apex of the cone as indicated by the dot and-dash lines in Fig. 4. In other words, the yarn will be built up in a mass which not only has a gradually increasing taper on its peripheral surface, but

certain advantages as well known in the winding art. First, it provides for a freer delivery of the yarn from the surface of the cone in unwinding it; and, second, the convexity of the base tends to prevent over runs or loose coils of yarn at this 'end of the cone. That is to say, where the yarn coils reverse at the base end of the conethey are supported in more stable relation and restrained from slippingout of place, thus preventing overruns, cobwebs or loose loops which would be apt to impede the free delivery of the yarn when it is drawn oil over the apexend of the cone.

As the cone-holder 2O rises from the driveroll 15 retrogressive movement is prevented by the action of the dog or pawl 56 onthe ratchet-sector 50. The roller 47 is therefore prevented from sliding back in the camgroove so that there will be no tendency for the cone-holder 20to vibrate or oscillate, its movement away from the drive-roll 15 being accomplished with a smooth and even action and its angle of inclination to the roll controlled positively. The double faces of the cam-groove 45 being constantly in engagement with the follower roller --47 pre-' vent playor lostmotion between the parts,

none on the drive-roll and therefore the yarn is disposed in smooth level layers to form a uniformly dense, compact package of true contour in accordance with the prescribed degree of taper on its surface and convexity at the base.

My present invention, while similar in some respects to the machine of the patent 'hereinbefore referred to embodies improvements thereover in the construction and method of operation of the parts. As one particular feature ofimprovement the coneuilder mechanism is reduced to the simplest and most direct form by mounting the cone-holder on the swinging arm 30. The cam-track or guide 40 which controls the tilting action of the cone is of relatively short length and its control of the cone-holder through the roller 47, arm 46 and bearingmember 22. is made more direct, resulting'in a close coupling which eliminates backlash and lost motion and therefore insures a more positive action for the purpose described. Furthermore, the builder-motion is compacted and condensed within a-minimum space to reduce the dimensions of the whole machine. The simplicity of the mechanism also makes for greater ease of operation, and insures against its becoming deranged or getting out of order.
